What do you imagine a generated video about poetry would be?

>Every AI video demonstration is always about funny stuff and fancy situations.

The thing about AI slop is that by its very nature, unless it's heavily reined in by a human, it's invariably lowest common denominator garbage. It very likely will generate something you yourself could think of within the first five seconds of hearing the prompt, not some very clever take on it, so it can only work as a placeholder (AI as a replacement of stock images is great, for example) or to add background detail where it won't call attention to itself and its genericity.

>imagine building a video about the moment Jesus was born

Given there are multiple paintings on the subject, I very much doubt no one has generated something like that already.
